Canberra Nature Mapr: Species Richness Score (SRS)
Canberra Nature Mapr (formerly Map) has introduced a new feature to record biodiversity in nature reserves and other areas, the Species Richness Score, see here.
CNM currently records 10,151 entries for Mount Majura, dating to the 1990s, when old records from the ACT Wildlife Atlas were added. More recently, 5380 records with photos have been added.
Many of the CNM records are for the same species, recorded at different times and locations. SRS summarises this information, weighting their status as native or exotic. There is a dashboard for Mount Majura, where you will find the current records status and a graph showing changes over recent years.
For Mount Majura, the SRS is now rated 3100 for the reserve’s 553 hectares, and it has been steadily increasing over the last few years. The graph also shows the recent survey effort in sightings per hectare; the cumulative survey effort listed as 18.35 species per hectare. There is also a colourful wheel showing the species, see below. When you visit the CNM web page, put your cursor over a section to find the exact number of recorded species e.g. 603 species of plants, at the top half of the wheel.
If you compare the wheel for Mt Ainslie with Mt Majura’s, interestingly, nearly half the species on the Ainslie wheel are insects: so we have many more insects to record on Mt Majura! |
